The 1+N-pole format with C 40 characteristic means it protects a single-phase final subcircuit against both earth leakage and overcurrent, tripping at 5x to 10x rated current for short-circuit faults. The 70 mm width (4 module spaces) fits standard DIN-rail enclosures — plan for the space when populating a distribution board. The 30 mA rated residual operating current (IΔn) is the standard threshold for personal protection against indirect contact and supplementary protection against direct contact in TN and TT systems. Type AC detection responds to sinusoidal AC earth faults — fine for general socket-outlet and lighting circuits where non-sinusoidal leakage is unlikely. The C 40 overcurrent characteristic (C-curve, 40 A rated) is sized for circuits with moderate inrush — motorized loads, small compressors, or groups of fluorescent fittings — where the magnetic trip threshold of 200 A to 400 A avoids nuisance tripping on startup.","metaTitle":"Siemens 5SU1354-1LV40 FI/LS Protector, 30 mA, 10 kA, C 40","metaDescription":"Siemens 5SU1354-1LV40 FI/LS protector, Type AC, 30 mA, 10 kA, 1+N-pole C 40.
